# isSameFloat64Array

> Test if two arguments are both [Float64Arrays][@stdlib/array/float64] and have the [same values][@stdlib/assert/is-same-value].

<section class="usage">

## Usage

```javascript
var isSameFloat64Array = require( '@stdlib/assert/is-same-float64array' );
```

#### isSameFloat64Array( v1, v2 )

Tests if two arguments are both [Float64Arrays][@stdlib/array/float64] and have the [same values][@stdlib/assert/is-same-value].

```javascript
var Float64Array = require( '@stdlib/array/float64' );

var x = new Float64Array( [ 1.0, 2.0 ] );
var y = new Float64Array( [ 1.0, 2.0 ] );
var bool = isSameFloat64Array( x, y );
// returns true

bool = isSameFloat64Array( x, [ 1.0, 2.0 ] );
// returns false
```

<section class="notes">

## Notes

-   In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the [same value][@stdlib/assert/is-same-value].

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var Float64Array = require( '@stdlib/array/float64' );
var isSameFloat64Array = require( '@stdlib/assert/is-same-float64array' );

var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var y = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var out = isSameFloat64Array( x, y );
// returns true

x = new Float64Array( [ -0.0, 0.0, -0.0 ] );
y = new Float64Array( [ 0.0, -0.0, 0.0 ] );
out = isSameFloat64Array( x, y );
// returns false

x = new Float64Array( [ NaN, NaN, NaN ] );
y = new Float64Array( [ NaN, NaN, NaN ] );
out = isSameFloat64Array( x, y );
// returns true
```
